The way in which an object or living thing is shaped and its substructure determine many of its properties and functions. Stability and Change

For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study.

Patterns Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them. Cause and Effect: Mechanism and Explanation Events have causes, sometimes simple, sometimes

multifaceted. A major activity of science is investigating and explaining causal relationships and the mechanisms by which they are mediated. Such mechanisms can then be tested across given contexts and used to predict and explain events in new contexts.
